Abstract: 1,188,579. Bottle openers. T. CAMPAGNOLO. 7 Aug., 1967 [5 Aug., 1966], No. 36193/67. Heading B8T. A bottle opener comprises an axially slidable and rotatable corkscrew 8 inside a main body 1 having a coaxial bell-shaped extension 2, 3 at its lower end, the extension having a shoulder 14 to engage the top of the body and the length of the extension 2, 3 being greater than the diameter of its mouth 4. As shown, the bell-shaped extension consists of an outer sleeve 3 slidable on a fixed sleeve 2. The sleeve 3 is slidden manually downwardly along the fixed sleeve 2 against the bias of a spring 9 to engage a knurled ring 4 of resilient material at its mouth with the neck of a bottle, and thus centre the corkscrew. Alternatively, the sleeves 2, 3 may be replaced with a unitary sleeve. Rotation of a handle 6 to drive home the corkscrew 8 slides a rack 7 axially and acts through toothed wheels to pivot handles 5 upwards to the position shown. The cork is then withdrawn from the bottle by grasping both the handles 5 and pivoting them downwards.

In a brake actuating mechanism comprising a primary lever 12 and a secondary lever 14, the primary lever 12 engages at one end with the actuated rod 10, is coupled at an intermediate point 16 in its length to a force-applying member 15, and is pivoted at its other end 13 to one end of the secondary lever 14 which is pivoted at its other end on a stationary pivot 17, and the secondary lever is coupled to the actuated member 10 by a one-way ball clutch. On initialmovement of the member 15, the lever 12 pivots about its end 13 and draws the rod 10 through the one-way clutch until all clearances have been taken up. On further movement of the member 15, the lever 14 pivots about the point 17 and carries the rod 10 with it through the engagement of the one-way clutch. The clutch comprises a ring of caged balls 27 located between the rod 10 and an internally coned sleeve 24, the balls being urged towards the smaller end of the sleeve bore by a light spring 25. The ball cage bears against the end of an adjustable sleeve 27 just before the lever 14 is returned to its stop 22 thereby releasing the grip of the balls 23 on the rod 10.

Filed: 1938-12-14
Abstract: 523,777. Rolling. BISS, R. Dec. 14, 1938, No. 36500. [Class 83 (iv)] Mills for heavy reductions in the cold with small rolls, have one or both operating rolls supported by two or more auxiliary rolls the outermost rolls being in rolling contact with a rotary support ring running in bearings in the housing. On account of the reverse rotation of the lower roll 2 this is provided with additional intermediate rolls 6, the rolls 1 and 6 being supported by rolls 4, 5 supported by rings 7 which form the outer members of ball races the inner members being the housing. The rings 7 have teeth and are driven by gears on a shaft 32. The bearings of one of the rolls 5 are mounted for adjustment at right angles to a radius of the rings to vary the effective pass. In a modification only one small working roll is employed and pass adjustment is effected by screw operated wedges 31 Fig. 4. In another modification the bearings of the lower support rolls are in aligned radial guides in a member 15, Fig. 3, fewer supporting rolls being required. In another modification the member 15 is replaced by two members so that the angle between the guides may be varied for pass adjustment. The rings 7 may form the inner members of the ball race or may be supported by rollers or pads. The rings or the rolls or both may be driven and the work is preferably traversed independently, one of the drives being non-rigid as to speed.

Abstract: 1,064,337. Dispensing articles. HITACHI Ltd. Aug. 19, 1965 [Jan. 27, 1965], No. 35648/65. Heading A4T. [Also in Division B6] In a card vending machine the cards are stored in a ribbon of envelopes folded fanwise, the ribbon being led up through guide 14 and feed rollers 11a, 11b to lift arm 15b and open switch SWb. The ribbon is fed into the vicinity of rollers 10a, 10b and moves arm 15a of switch SWa so that a motor driving the rollers via roller 10a is ready for operation when a coin operated switch is actuated. On pressing a selected switch for a card from one of several ribbons, rollers 11 feed the card into rollers 10 which have a higher peripheral speed so that as the card moves to the delivery opening between the envelope is torn by the tension between the rollers and as the card is ejected switch SWa is operated to allow a relay and the motor to feed the second card up to the rollers 10 to again operate switch SWa whereby the motor is switched off by a relay and the coin operated switch. As the last card is fed through rollers 10, switch SWb closes and lights sell-out lamp and as it leaves rollers 10, switch SWa closes the motor circuit. The switches are interconnected by rod 16 so that arm 15b may rise independently of 15a.

Abstract: 886,370. Mixing rubber. FARREL-BIRMINGHAM CO. Inc. Oct. 25, 1960 [Nov. 9, 1959], No. 36553/60. Class 86. [Also in Group XIII] Plastic material e.g. rubber is demoistured during treatment in a Banbury mixer comprising a mixing chamber 10 and rotors 11, 12 by subjecting it to pressure by the charging ram 20 which has sufficient clearance in the guideway 14 to allow liquid to pass above the ram. The upper surface 25 of the ram is inclined to direct the liquid into a drain tube and pipe 28, 29; to prevent material entering the tube 29 during charging, the opening 28 is normally closed by a sliding plunger 31 actuated by a fluid-pressure cylinder and piston 34, 33. The ram 20 is also actuated by a fluid-pressure cylinder and piston 23, 24 and carries a rod 26, Fig. 3 (not shown) which when the ram is in its lowest position closes an electric switch to withdraw the plunger 31, see Fig. 2 (not shown) and allow liquid to escape. The swinging door 16 of the loading shoot 15 may also be operated by the fluid-pressure system so that the door will be raised to its closed position as shown on descent of the ram, and lowered to its loading position when the ram is raised. A modified ram has an upper surface of inverted V shape, the drain tubes 29, 30 being duplicated. Reference has been directed by the Comptroller to Specification 852,173.

Abstract: 913,784. Angular bending. CHAMBERLAIN INDUSTRIES Ltd. July 7, 1961 [Oct. 25, 1960], No. 36652/60. Class 83 (4). A tube-bending machine comprises a rotary centre-forming die. and a back former bar between which the work is laid for bending around the die, a pressure-applying head, a driver and a means of supporting the driver and die whilst the former bar is disposed relatively of the support means during a bending operation. An eccentric reversible forming die 1 having an arcuately channelled periphery is adjustably pivoted about a pin 2 in holes 3, which are slightly off-set relative to the axis of a jack 7, in a pair of parallel bars 4, 5, welded at one end to a rectangular head 6 secured to an hydraulic jack 7 actuated by a lever 8. A forked head 9 slidably guided between the bars 4, 5 houses a roller 10 which bears against the flat face of a back-forming bar 11, the other face of which is arcuately channelled. A tube 12 is anchored by a stirrup 14 retained by a pin 15 at the starting end of the die 1, pressure due to the actuation of the jack 7 loads the roller 10 and former bar 11 and causes the die 1 to rotate and bend the tube to the required arc. The cylinder 7 may be detachable and the whole assembly stowed in a box 16 on which the machine may be mounted by means of a transverse bar 17 welded to the arm 5 and located on a spacer 19 between strengthening bars 18 and additionally supported by bars 20 and a flange 21. The jack may be connected direct to a source of fluid pressure. A feed-screw arrangement may be used in place of the jack.

The rim of the throttle valve 111 is thickened on that side which faces the idling and change-over jets and slits 112 are formed in the thickened portion. The thickened portion subtends an included angle of 30 degrees at the centre of the valve and the slits are 0.8 to 1.0 mm wide, so that the cross-sectional area of the two slits is 12 to 18% of the area of the thickened portion.

The nozzle 113 is clamped between the downstream face of the carburetter and the upstream end of the inlet pipe 25. The axial length h of the nozzle is equal to the diameter D of the passage through the carburetter. The cross-sectional area FA of the exit is 10 to 20% less than the area FE of the entry section. The axial length hw of the roughened section is half the length h and the depth hr of the roughening is 0.5 to 0.8 mm. when the diameter D is 28 to 40 mm.
